Tesla Motors: We're Going to Need to Sell More Stock, Again

Tesla Motors (NASDAQ: TSLA) plans to raise additional funds before the end of the year. The added cash will help fund the development of its upcoming Model 3 sedan and the ongoing build-out of its battery Gigafactory, the company said in a regulatory filing on Wednesday.

What Tesla said

In a filing with the Securities and Exchange Commission related to Tesla's proposed merger with Solar City (NASDAQ: SCTY), Tesla discussed the likely future liquidity needs of the combined company. That section included this statement (emphasis added):

Those additional funds, Tesla said, would be used to support several ongoing initiatives.

Why another round of fundraising isn't a surprise

It's not at all surprising that Tesla plans to raise more money by the end of the year. CEO Elon Musk had previously warned that the company might seek "a small equity capital raise" at some point, though the hint was that it wouldn't be necessary until 2017.

It's also not surprising because this is Tesla, and Tesla's ambitious plans are going to require a lot of cash. Just the automotive portion of Musk's latest "master plan, part deux" will almost certainly cost more than $10 billion to realize. (And remember that with an automaker, the huge product-development and tooling costs are paid up front, before a single product ships.)

At some point, the hope is that Tesla will be able to fund those plans out of its own profits. But that point won't come any time soon: Tesla lost $293 million in the second quarter, and there's not much chance of a dramatic swing to profitability before the Model 3 starts shipping. Tesla is just spending too much money.

What another stock sale will mean for Tesla investors

Every time Tesla sells more stock, analysts worry the dilution will hurt Tesla's share price. So far, those fears have proven unfounded. The market absorbed Tesla's most recent equity offering, on May 19, in stride.

It's likely Tesla isgoing to need several more not-so-small equity capital raises over the next couple ofyears. Fortunately for the company,Tesla's stock trades at a sky-high valuation that is more about the company's story and prospects than it is about fundamentals. As long as the story continues to inspire investors (and as long as nothing happens to make it seem wildly improbable), the market will probably be willing to support additional equity offerings.

That's Musk's hope, anyway.

What's next for Tesla

Assuming that shareholders vote to approve the merger with Solar City, the next big milestone for Tesla's core auto-making business will be the launch of the compact Model 3 sedan. That's currently expected to happen in the second half of 2017.

That launch will tell us a lot about how the subsequent phases of Tesla's plan will -- or won't -- unfold.
